    Abstract: In some embodiments, a method for processing an audio signal in an audio processing apparatus is disclosed. The method includes receiving an audio signal and a parameter, the parameter indicating a location of an auditory event boundary. An audio portion between consecutive auditory event boundaries constitutes an auditory event. The method further includes applying a modification to the audio signal based in part on an occurrence of the auditory event. The parameter may be generated by monitoring a characteristic of the audio signal and identifying a change in the characteristic.

    Abstract: Scaling, by a desired amount sm, the overall perceived loudness Lm of a multichannel audio signal, wherein perceived loudness is a nonlinear function of signal power P, by scaling the perceived loudness of each individual channel Lc by an amount substantially equal to the desired amount of scaling of the overall perceived loudness of all channels sm, subject to accuracy in calculations and the desired accuracy of the overall perceived loudness scaling sm. The perceived loudness of each individual channel may be scaled by changing the gain of each individual channel, wherein gain is a scaling of a channel's power. Optionally, in addition, the loudness scaling applied to each channel may be modified so as to reduce the difference between the actual overall loudness scaling and the desired amount of overall loudness scaling.

    Abstract translation: 通过将每个单独信道Lc的感知响度缩放基本上等于所需量的量，将感知响度定为信号功率P的非线性函数，以期望量sm缩放多声道音频信号的整体感知响度Lm 在所有频道sm的整体感知响度的缩放，受到计算的准确性和整体感知响度缩放sm的期望精度。 可以通过改变每个单独信道的增益来缩放每个单独信道的感知响度，其中增益是信道功率的缩放。 可选地，另外，应用于每个通道的响度缩放可以被修改，以便减小实际的整体响度缩放与期望的总响度缩放量之间的差异。

    Abstract: An audio processing system and method which calculates, based on spatial metadata of the audio object, a panning coefficient for each of the audio objects in relation to each of a plurality of predefined channel coverage zones. Converts the audio signal into submixes in relation to the predefined channel coverage zones based on the calculated panning coefficients and the audio objects. Each of the submixes indicating a sum of components of the plurality of the audio objects in relation to one of the predefined channel coverage zones. Generating a submix gain by applying an audio processing to each of the submix and controls an object gain applied to each of the audio objects. The object gain being as a function of the panning coefficients for each of the audio objects and the submix gains in relation to each of the predefined channel coverage zones.

    Abstract: FIG. 1 is a front perspective view of a sound reflector showing our new design;
    FIG. 2 is a front elevation view thereof;
    FIG. 3 is a rear elevation view thereof;
    FIG. 4 is a right side elevation view thereof;
    FIG. 5 is a left side elevation view thereof;
    FIG. 6 is a top plan view thereof; and,
    FIG. 7 is a bottom plan view thereof.
    The dashed broken lines in the figures illustrate environment and portions of the sound reflector that form no part of the claimed design.
    The sound reflector is shown with a symbolic break in its length. The pairs of adjacently-spaced jagged dot-dash broken lines in the figures form no portion of the claimed design. The appearance of any portions between such pairs of adjacently-spaced jagged, dot-dash broken lines forms no part of the claimed design.
